Ubuntu16.04环境下通过Cmake管理Opencv项目

1、新建qt cmake工程

New Project -> Non-Qt Project -> Plain C++ Application

2、CMakeLists.txt文件内容修改为如下：

//gh
project(untitled2)

# 添加c++ 11标准支持
set( CMAKE_CXX_FLAGS "-std=c++11" )

# 寻找OpenCV库
find_package( OpenCV REQUIRED )
# 添加头文件
include_directories( ${OpenCV_INCLUDE_DIRS} )

# add sourcce files: *.cpp
aux_source_directory(. SRC_LIST)

add_executable(${PROJECT_NAME} ${SRC_LIST})

# 链接OpenCV库
target_link_libraries( ${PROJECT_NAME} ${OpenCV_LIBS} )

3 、main.cpp内容为：

#include <iostream>
#include<opencv2/opencv.hpp>
using namespace std;
using namespace cv;
int main()
{
   Mat image = imread("ubuntu.png",IMREAD_COLOR);
   if(image.data == nullptr)
       cout<<"files doesn't exist"<<endl;
   else
       cout<<"success!"<<endl;
   cout << "Hello World!" << endl;
   imshow("test",image);
   waitKey ( 0 );                  // 暂停程序,等待一个按键输入
   return 0;
}

4、工程项目右键依次执行：

build -> run
